IMPROVEMENT IN COAL-STOVES.

Specification forming part of Letters Patent No. 82,637, dated September29, 1868.

6| To all whom "it may concern:

Be it known that I, ALBERT J. REDWAY, of Cincinnati, of Hamilton county,Ohio, ha'veinvented certain new and useful Improvements inGannon-Stoves; and I hereby declare the following to be a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, making part of this specification. v

My invention relates to a smoke-consuming device for heating-stoves; andit consists of a reverberating plate or crown suspended centrally overthe fire in such a manner as to arrest the central currentof the smoke,and to leave an annular space therefor between said plate and the sidesof the stove, and in connection therewith an annular canopy or cowlwhich deflects the flame to the center of the stove and protects theRussia-iron drum or casing from extreme heat; and my invention furtherconsists in making said crown-plate adjustable in distance from thecowl, so as to widen or contract the smoke-throat to suit particulardrafts or ditt'erent kinds of fuel.

In the accompanying drawings, Figure 1 is a sectional view, partly inelevation, of a cannon-stove embodying my improvements. Fig.

, 2 is a vertical section,on an enlarged scale, of

my improved fire-door.

A is the fire-chamber, and B the customary Russia-iron drum. (J is acast-iron crown or hood resting upon lugs 0, within the mouth of thefire-box A, as shown, and slotted to receive the bars d d of thependentreverberating plate D. The plate D is preferably slightly concaveon the under side, and its supports d d are pertorated in several placesand provided with links or pins (1, for the purpose of adjustmentvertically, in order that the smokethroat may be widened or contractedto suit the various requirements of fuel, &c. The

plate D is of heavy cast-iron or of fire-tile capable of retaining heatand igniting the product of fresh fuel before it escapes into the drumB. The form and position of this, plate also causes the smoke toreverberate, the tend ency of the plate being to collect the gases 'atits center before allowing them to escape atits periphery. The issue atthe top of the crown G is much smaller in diameter than the drum B, andthe flame is thus kept from too close contact with the Russia iron ofthe drum B.

\Vhile preferring to make the central crownplate adjustable in height, Ireserve the right to fix it permanently within the stove, if (10- sired.

The door E, through which fuel is intro duced to the fire-chamber A, isfurnished with the customary mica or'other transparent front, F, andthis sheet F extends entirely across the door from side to side, but itdoes not quite reach the bottom of the same, a space, 6, being leftbetween them. Placed in the rear of the mica F is a perforated metallicplate, Gr, a

space, f,'being left between them, so as to ad-' mit of a currentof airpassing between the 1 two. When a fire is started in the stove aconstantcurrent of air passes through the spaces 0 andf, and alsothrough the apertures in the plate G, as indicated by the blue arrows inFig. 2, by which means the smoke and heat are diverted away from themica, and the latter is thus prevented from becoming smoked and cracked.

I claim herein as new and of my invention- The central crown-plate, D,having perl'ora ed bars d d, by which it is adjusted relatively to theannular cowl U, substantially as shown and described.

In testimony of which invention 1 hereunto set my hand.

ALBERT J REDVVAY.
